To all whom t 'may concern.'

citizen of the United States, and a resident of the township of Cranford, in the county of Union, State of New Jersey, have invented certain new and useful improvements' in Supplement Holders' for Books, of which the following is a specification.

The improvements'relate to the book binding art, and more particularly to bindings for books containing' matter which is sup plemented, amended,or added to after the publication of the original volume, and the objects of the improvements to provide a cover for such a bookv which willserve all the ordinary uses and purposes of such a cover,'and which will also provide means for adding to such volume and connecting therewith in proper position and relation one or more supplements or addenda. In carrying out these improvements the cover of the original volume and the cover of the supplement are made of suchv ports or decisions; and codified or digestedV laws, decisions or rulings, which are sub]ect.

to later amendment, change, or interpretation. y

Volumes containing such matter are pubf lished and are used by various classes of persons and for `various purposes, and supplements givinglater information affecting the matter in the Aoriginal volume are frequently published later, and usually at stated periods, for the information of those who have the original publication; and it is important that the original volume and the supplement giving later information concerning its contents shall be connected and associated in such a manner that one will, and may conveniently, be consulted with the other. Information of service of the kind indicatedvis usually sold by subscripare primarilyv tion, the subscription entit-ling the subscriber to an original volume and supplements the-reto published quarterly, semi-annually, or regularly after the lapse of some other specified period, andthe subscriber is usually instructed to consult the supplementbefore or after reading the particular pore tion of the original volume in which he may be interested. But it frequently happens that supplements arev lost or vmislaid or the wrong. supplement is consulted; and it is therefore important that the original volume and the proper supplement shall be so connected and arranged that this cannot happeny if ordinary care be exercised. The principal object of the present improvements is therefore to provide for the proper and secure, yet quickly detachable connection and association of a. volume and vone or more supplements thereto, so that both may be treated practically as one volume and consulted as one work.

The improvements are illustrated in the accompanying drawings, referred to herein, and in whichl Figure l is a side elevation of a bound volume and supplement embodying the improvements; Figure 2 is a like view of the same with the supplement turned out to expose the cover of the book, and a portion of the book cover broken away to show the connection between book and supplement g Figure 3 is a transverse section on the line 3 3 of Figure 1, as indicatedY in that figure; Figure 4 is an enlarged Vdetail in cross-sectionfof the front of the book cover, asillustrated in Figure 3.

The book consists of the desired number of signatures 1, bound at one edge as indicated at 2, and united at the back 5 with a case cover comprising boards 3 and cover of cloth or other suitable material 4.

The portion ofthe cover la which extends over the outer face of the front board 3 is not secured thereto, but has its inturned edges glued to the inner face thereof and is otherwise free from the said board. It has however asheet of thin libre board 6 or other similar material pasted to its under side, and has its inner edge turned over and pasted along the under side of this sheet. This sheet 6 is not connected with the front board except through the material of the front cover as just described, thus leaving a pocket `between the reinforced cover and the front board of the case cover, and as the cover la is not secured to the outer face of the board and along the inner edge is cured only to its reinforcing strip a mouth for this pocket is thus provided along the hinge or joint- 7 and slightly forward thereof.

The supplement consists of leaves S secured at one edge to the back of a cover 9 preferably of tough paper, and the back of this cover 9a is cut short of the outer edges of the leaves and tapered from a point near the back to its outer edge, so as to form a tongue or flap to be inserted in the pocket.

In order to secure the supplement to the book it is only necessary to slip the tongue 9a in the pocket as far as it will go, and in this position the back of the supplement cover will be aligned with the joint or hinge 7 of the book and the flap held by frictional coaction and contact of its top and bottom edges with the inside edges of the pocket against movement in all directions. When the supplement is opened the back will enter the depression at the joint, and at all times the bead or ledge l0 will aid in preventing the supplement from slipping out of position. To remove the supplement it is only necessary to draw the tongue or llap 9a from the pocket, and a supplement may be removed and a new one inserted in its place in a few moments. In case it should become necessary or advisable to add a new supplement without removing a previous one this can be done by simply inserting the tongue of the new supplement in the pocket beneath the tongue of the old supplement. The supplement is made slightly smaller than the cover of the original volume, but the leaves are of substantially the same length as the leaves of the original, and only slightly narrower so that the volume with one or more supplements or addenda has substantially the appearance and the convenience of a single volume.

The reinforcing sheet 6 of the covering material la is normally in contact with the outer surface of the front board so that anything inserted in the pocket will be held therein by the covering material which must be stretched to some extent to receive it, and as the pocket is therefore too small to receive the supplement it is not possible for the user to insert the supplement therein. The printingmatter of the volume and supplement is arranged in the usual maner so as to read from front to back, and as the pocket is on the exterior of the front cover and the tongue is on the back of the supplement, when the tongue is inserted in the pocket the volume and supplement will be in proper position and relation to each other.

What I claim is:

l. A book and supplement comprising a volume having leaves bound together at one edge and secured at said edge to a case having a back with laterally projecting edges and front and back covers, a pocket formed by a piece of covering material secured to the outside of the front cover only along the front, top and bottom edges thereof and opening at the edge adjacent the back, and a supplemental volume consisting of leaves secured together and a tongue to which said leaves are secured along one edge, said tongue extending from said edge toward the opposite edge and formed to it said pocket, and the edges of the tongue and leaves which are secured together being adjacent to and inside the side edges of the back.

2. A book and supplement comprising a volume having leaves bound together at one edge and secured at said edge to a case having a back and front and back covers, a pocket formed by a piece of covering material secured to the outside of the front cover only along the front, top and bottom edges thereof and having its mouth at the edge adjacent the back, and a supplemental volume consisting of leaves secured together and a tongue to which said leaves are secured along one edge, said tongue extending from said edge toward the opposite edge and formed to fit said pocket, and said back having a bead normally opposed and in proximity to the mouth of the pocket and the back of the supplemental volume when in place.

3. A book and supplement comprising a book proper, consisting of leaves and a cover to which the said leaves are bound along one edge, a back to which said edges are secured. said back having a side portion extending beyond the outer surface of the cover along its bound edge, a pocket on the exterior of said cover having its opening in proximity to the bound edge of the cover and within the extending portion of the back, and a supplement comprising leaves bound together at one edge, a tongue bound to said leaves at the same edge and formed to lit said pocket, the said supplement leaves being formed and arranged to lie on the outside of said pocket when the tongue is therein and to open at the same edge as the leaves of the book, but being openable without opening the book cover.

4. A book and supplementcomprising a main volume consisting of leaves and a front and back cover bound together near one edge in such a manner as to leave a projecting ridge extending beyond the outer surface of a cover along the said edge, a pocket formed on the exterior of the said cover and having a mouth adjacent to and substantially parallel with said ridge, but spaced therefrom a suflicient distance to accommodate the back or bound edge of a supplement, a. supplement also consisting of leaves bound together near one edge and a cover bound therewith along the said edge forming a tongue of a size and shape to it the said pocket, the said supplement having a portion extending from said binding to its adjacent edge of a size and shape toit between the mouth of said pocket and the said ridge of the main volume, whereby the supplement is held normally against movement in all directions in position on the main volume7 but may be removed therefrom and replaced by flexing the materials with the fingers.
